Tutorial: How to use LCD Display Module LCD2002 20×2

The LCD 20×2 module is an essential component for displaying text and data in Arduino projects. Ideal for beginners and makers who want to add a display to their device.

What you need

• Arduino Uno or compatible
• USB cable to connect the Arduino to the PC
• Trainable connections (jumpers)
• 5V power supply battery

Steps

1. Connect the VCC and GND pins of the LCD module to +5V and GND of the Arduino.
2. Connect the RS pin of the LCD module to digital pin 12 of the Arduino.
3. Connect the RW pin of the LCD module to GND of the Arduino (RW is not used, so it is connected to ground).
4. Connect the E pin of the LCD module to digital pin 13 of the Arduino.
5. Connect pins D4-D7 of the LCD module to the respective digital pins 5-8 of the Arduino.
6. Include the LiquidCrystal.h library in the Arduino code.
7. Create a LiquidCrystal object for the display and set the configuration (number of rows, columns).
8. Send text to the LCD module screen.

Example code

// Includere la libreria
#include <LiquidCrystal.h>
// Definire l'oggetto LiquidCrystal
LiquidCrystal lcd(12, 13, 5, 6, 7, 8);
void setup() {
    // Impostare il display a 2 righe e 20 colonne
    lcd.begin(20, 2);
    // Mostrare un messaggio di benvenuto
    lcd.print("Benvenuti Maker!");
}
void loop() {}

Mini project

Create a simple console that displays temperature and humidity by reading data from a DHT11 sensor.

Common mistakes

• Incorrect pin connection of RS, E or RW
• Forget to include the LiquidCrystal.h library
• Set the number of rows and columns incorrectly in the begin() method
• Do not send data to the screen

Recommended accessories

• DHT11 sensor
• RTC DS3231 module
• Breadboard 830 points
• Trainable connections (jumpers)
